Title: Improvements in or relating to fuel-air mixture regulators for internal combustion engines
IPC: F02M23/03
Filed: 1934-12-20
Abstract: 431,443. Spray carburetters; chargeforming devices. STARY, F., 60, Wiednerg³rtel, Vienna. Dec. 20, 1934, No. 36501. Convention date, Dec. 22, 1933. [Classes 7 (ii) and 7 (iii)] An electric switch 6, operated by the throttlevalve control rod 2 through a friction clutch 4 and closed by any closing movement of the throttle 1, completes an electric circuit including a solenoid 11, and when the current produced therein by the engine-driven generator 8 is sufficiently large, the solenoid lifts to the open position balanced valves 12 which admit air to the induction pipe through a pipe 13 connecting therewith adjacent the throttle valve 1 either on the engine side or the carburetter side thereof, a second pipe 14 being provided in the latter instance to avoid excessive suction on the idling nozzle. A spring 18 closes the valves when either the electric circuit is broken by opening the throttle valve or the engine speed is too low to generate sufficient current to keep the solenoid effective. A fuel valve 20 may be associated with the stem of the valves 12 and be raised thereby to supply additional fuel to the carburetter to avoid over-dilution of the mixture.

Title: Print actuating member control mechanism
IPC: B41J2/27
Filed: 1955-12-21
Abstract: 827,962. Selective printing. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 21, 1955 [Dec. 30, 1954], No. 36613/55. Class 100(4) In a printing apparatus wherein each character impression is effected through the impact stroke of a respective spring- operated print actuating member 34 the latter is controlled by a mechanism comprising a first cam system 40 cyclically operable to release and then restore the member, a second cam system 46 operable in synchronism with the first system, a follower 48, 50 for the second system, print suppressing means 56 biased to a normal position out of the path of the actuating member 34 but movable to a position in which it obstructs the print-effecting movement of the actuating member, a link 52 pivotally connected with the cam follower, and interposer means 54 operable to connect the print suppressing means 56 with the link 52 for movement from the normal position to the position in which it obstructs the actuating member 34. In the wire printer shown spaced print heads 10, each with wires 14, are mounted in a row on a transverse sliding carriage 16, and are moved against the ribbon 24, paper 22, and platen 20 by drive wires 26, the latter being operated by movement of arms 34 under the control of springs 42 and cams 40 with depressions 40b. The high portions 46a of cams 46 operate on rolls 48, at the same time as depressions 40b move beneath rollers 38, to rock bellcranks 50 which in turn slide links 52 forwardly and rearwardly, slots 53 in the links engaging interposers 54 movable in and out of the ends of universal bar 56 slidable forwardly and rearwardly in the machine and normally urged rearwardly by springs 62. When magnet 82 is energized (e.g. during idling periods) the armature 82b is moved and acts through 86a, 86, 90 to pivot levers 92, against the pull of springs 96, and the levers press interposers 54 inwardly, against springs 74, so that interposer plates 54b engage in slots 53. Bar 56 then partakes of the movement of links 52 and moves forwardly to engage, and displace slightly forward, all the arms 34 as the latter are freed by cams 40, preventing actuation of the arms by springs 42. Suppression of a particular actuating member 34 is effected by manual movement of the appropriate lever 100 to the forward of its two positions, the lever acting via spring 108 to turn the associated operating lever 106 clockwise, Fig. 1, so that the downturned lip 106a is positioned on the upper edge of the corresponding member 34 if the latter is in its normal position, but moves to a position in which it interrupts the member 34 when the latter is moved forwardly by bar 56. With the member 34 thus intercepted the associated roller 38 rides clear of cam 40, reducing wear, noise &c. Lever 106 is returned by bar 56 after the associated lever 100 has been moved to its rearward position. Specification 819,467 is referred to,

Title: Method of clarifying impure water
IPC: B01F25/46
Filed: 1973-08-02
Abstract: 1444026 Dispersing gases in liquids WATER RESEARCH CENTRE 2 Aug 1973 36854/73 Heading B1C In a method of clarifying floculated impure water by dissolved gas flotation, pressurized gas-saturated water is discharged into the water to be treated through a nozzle comprising a chamber having constricting inlet and outlet orifices so arranged that the gas-saturated water undergoes a substantial change in direction and loss of pressure whereby bubbles are released. As shown the chamber 10 is formed by discs 2, 3 having inlet and outlet orifices 4, 5, the latter being the larger. The reduction in pressure on passage through orifice 4 and the turbulence caused by sticking the walls of the chamber causes gas to come out of solution in the form of fine bubbles. The chamber may discharge through a shroud 12 with the water to be treated. The gas is conveniently air, and the floc may be formed by treatment with an iron or alumimum coagulent.

Title: Improvements in or relating to a rotor blade pitch control mechanism for helicopter aircraft
IPC: B64C27/54
Filed: 1958-11-19
Abstract: 894,594. Helicopters. VYZKUMNY A ZKUSEBNI LETECKY USTAV. Nov. 19, 1958 [Nov. 29, 1957], No. 37239/58. Class 4. A helicopter comprises a hub on a rotor shaft, at least two blades having shafts connected to the hub through universal joints including axes offset from the rotor shaft axis and parallel thereto, each blade being angularly displaceable about its longitudinal axis, a member surrounding the rotor shaft and movable from a position concentric therewith to a position eccentric thereto, levers connected one to each blade shaft, and a link for each blade, the links being connected to the member at positions offset from the rotor shaft axis and connected to the levers at positions offset from the said axes of the universal joints, so that when cessation of power supplied to the rotor shaft causes the blades to move angularly about the said axes of the universal joints, the levers effect a change in blade pitch. Fig. 1 shows a rotor hub 1 in which is journalled on axis Z-Z, a universal joint member 7. The shaft 2 of a rotor blade is attached to member 7 through a pitch change bearing and a flapping axis. The pilot controls the blade pitch by displacing a member 6 vertically for collective pitch change, and horizontally for cyclic pitch change. A link 4 (see also Fig. 3) is pivoted at one end to member 6 by a joint 5, and at its other end to a lever 3 on the blade shaft by a joint 8, there being one link for each blade. If member 6 is held stationary relative to the hub, the forward movement of the blade about its drag hinge Z-Z, which occurs on engine failure and loss of driving torque, causes a decrease in blade pitch which completely or partly alters the pitch to that suitable for autorotation. Specification 648,777 is referred to.

Abstract: 1446206 Shearing HURCO MTG CO Inc 8 Aug 1973 [14 Aug 1972] 37646/73 Heading B3W A shear comprising two pairs of blades disposed for cutting a corner notch in sheet material has means for adjusting the cutting clearance between the blades of each pair. The upper blades 36U, 37U are mounted on a ram 11  adjustable to vary the clearances CF and CS Fig. 5, by vertical adjustment of wedges 46, 47 and wedges 39, 41 respectively. The wedge 41 is moved by means of a screw 148, Fig. 8, driven by engagement of a worm in a gear box (151) with a pinion in the screw shaft Fig. 7 (not shown). Wedges 39, 46, 47 are similarly adjustable by means of gear boxes (169), (168) and (154) respectively. The worms of gear boxes (154) and (168) are releasably connected by a shaft (171) and each worm has an extension such as shaft (176), Fig. 10 (not shown), which can be rotated by a wrench (182) so that simultaneous adjustment of both wedges 46, 47 can be made at either end of the shaft (171). A shaft (173) allows similar simultaneous operation of gear boxes (151), (169). The wedge 41 is urged against a vertically fixed guide block 43 by a spring 162. Wedges 39, 46, 47 are similarly urged against vertically fixed guideblocks 42, 48 and 49 respectively. Gauge bushings 187, 188, Fig. 1, are provided for the clearance CF and bushings 189, 191 for the clearance CS for use with a gauge pin and an indicator gauge (197), Fig. 10, which is removed during shearing. The guideblock 43 abuts a slide block 33 on the blade 36U and any play between the block 33 and the block 43 is taken up by a block 198 urged against the block 33 by hydraulic cylinders 199. Guide blocks 42 and 48 are similarly urged against a slide block 34 on blade 37U. Play between the slide block 33 and the guide block 49 is taken up by a hydraulicallyactuated pivotable block (204), Fig. 11 (not shown). A block 38 reinforces the joint between blades 36U and 37U. Hold downs 116 disposed end-to-end along both blade pairs are each operated by two hydraulic cylinders 123 and a return spring (131), Fig. 12. There is a continuous upward rake on the upper blades from point 36R to point 37P. The ram 11 is driven through cranks 64, 77 and 84 and links 73, 74 and 93 from a crankshaft 62 rotated by either of cylinders 68 and 69, Fig. 1. The full stroke cylinder 68 causes both blades 36U and 37U to move through a shearing stroke and half stroke cylinder 69 causes only blade 36U to do so. Each cylinder may be supplied with pressure at 1000 or 2000lbs p.s.i. A spring loaded, hydraulically released shear pin (101), Fig. 4 not shown, locks the ram against unintentional lowering.
